class_docstr: Container for cluster load metrics.
  
  Metrics here are updated from raylet heartbeats. The autoscaler
  queries these metrics to determine when to scale up, and which nodes
  can be removed.
docstr: Return a list of node resources (static resource sizes).
  
  Example:
      >>> from ray.autoscaler._private.load_metrics import LoadMetrics
      >>> metrics = LoadMetrics(...) # doctest: +SKIP
      >>> metrics.get_node_resources() # doctest: +SKIP
      [{"CPU": 1}, {"CPU": 4, "GPU": 8}]  # for two different nodes
